Description

TECHNICAL FIELD

[0002] Traditional electric energy meter measurement fault discovery means mainly include weekly inspection, initial inspection, meter reading by meter reading personnel, electric quantity accounting exception, and electric power inspection. Such inspection methods result in long duration of measurement faults and failure to discover the faults in time, which easily causes losses to both power supply and power consumption sides, and even affects safe power supply. With the progress of science and technology, a measurement automation system can realize real-time collection, monitoring, analysis and processing of electric energy information of a measurement meter, and can quickly find measurement faults.

[0003] Although the multifunctional electric energy meter currently used has a voltage loss alarm function, it does not have a function of judging and alarming voltage abnormally high or low of the electric energy meter, and does not separately store and count fault time, electric current, voltage, power, electric quantity and required compensation electric quantity. Moreover, due to limited storage space of the electric energy meter, the electric energy meter stores historical electric quantity data at an interval of one minute, and the time is generally one year. If the voltage abnormal fault is not found and processed for a long time, and the storage time period of the electric energy meter is exceeded, it is difficult to accurately confirm the fault time by reading the electric energy meter data by using a computer on site, thereby affecting accurate compensation electric quantity.

[0030] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0031] The metering automation system has the function of analyzing the collected data to determine whether there is a metering abnormal phenomenon. Since the data is stored in the database, there is no time limit, but due to the huge number of electric energy meters, the interval of the electric energy meter data collected by the automation system is 15 minutes. If the voltage abnormality needs to be compensated within 15 minutes, the compensation time cannot be accurately determined. If the voltage fluctuation is abnormal, the average value of the 15-minute voltage data in the fault period for the compensation power will also cause the compensation power to have errors, and the larger the user mutual inductor ratio, the larger the error, which seriously affects the correctness and fairness of the compensation power in the extreme case.

[0032] Embodiment one

[0033] Figure 1 is a flow chart of a method for determining the compensation power of an electric energy meter provided in embodiment one of the present application. The present embodiment can be applicable to the case of determining the compensation power of the fault period. The method can be executed by a device for determining the compensation power of an electric energy meter. The device can be realized in the form of software and / or hardware, and can be realized by an electronic device, which can be a mobile terminal, a PC terminal or a server, etc. Specifically, the method comprises the following steps:

[0034] S110, collect first electric energy data of the electric energy meter every first preset time.

[0035] The first electric energy data includes voltage, current, power and electric quantity of three phases. The first preset time can be a preset time period, for example, 15 minutes, 30 minutes, etc. The first preset time is not limited herein. The three phases can include phase A, phase B and phase C. The electric quantity can be the electric quantity generated in the first preset time.

[0036] In S120, when it is determined that the electric energy meter is in a working state according to the current of the three phases, the wiring type of the electric energy meter is acquired.

[0037] The wiring type includes three types: three-phase three-wire, three-phase four-wire high-supply high-metering and three-phase four-wire high-supply low-metering. The way of determining that the electric energy meter is in a working state according to the current of the three phases can be: comparing the current of each phase with the rated current of a set proportion, and determining whether the electric energy meter is in a working state according to the comparison result. The set proportion can be 0.5%. Specifically, if the current of each phase is greater than 0.5% of the rated current, it indicates that the electric energy meter is in a working state. If the current of one phase is less than or equal to 0.5% of the rated current, it indicates that the electric energy meter is in a non-working state.

[0038] In S130, if the voltage in the continuous set number of first electric energy data meets the abnormal condition corresponding to the wiring type, it is determined that the voltage of the electric energy meter is abnormal in the fault period.

[0039] The fault period is the period in which the continuous set number of first electric energy data is collected. The set number is preset, for example, 8. In this embodiment, if the wiring type is three-phase three-wire, the abnormal condition is that the absolute value of the difference between the voltage of phase A and the voltage of phase C is greater than or equal to a first set value. If the wiring type is three-phase four-wire high-supply high-metering, the abnormal condition is that the maximum value among the voltage of phase A, the voltage of phase B and the voltage of phase C is greater than a second set value, and the absolute value of the difference between the smaller two-phase voltages is greater than a third set value. If the wiring type is three-phase four-wire high-supply low-metering, the abnormal condition is that the maximum value among the voltage of phase A, the voltage of phase B and the voltage of phase C is greater than a fourth set value, and the absolute value of the difference between the smaller two-phase voltages is greater than a fifth set value.

[0040] The first set value can be set to 2V, the second set value can be set to 55V, the third set value can be set to 5V, the fourth set value can be set to 210V, and the fifth set value can be set to 20V.

[0041] Specifically, when the connection type of the electric energy meter is three-phase three-wire, if the voltage of the eight first electric energy data successively collected all satisfy the following condition: the absolute value of the difference between the A-phase voltage and the C-phase voltage is greater than or equal to 2V, it is determined that the electric energy meter has voltage abnormality in the fault period, otherwise, the electric energy meter does not have voltage abnormality. When the connection type of the electric energy meter is three-phase four-wire high-supply high-metering, if the voltage of the eight first electric energy data successively collected all satisfy the following condition: the maximum value among the A-phase voltage, the B-phase voltage and the C-phase voltage is greater than 55V, and the absolute value of the difference between the smaller two-phase voltages is greater than 5V, it is determined that the electric energy meter has voltage abnormality in the fault period, otherwise, the electric energy meter does not have voltage abnormality. When the connection type of the electric energy meter is three-phase four-wire high-supply low-metering, if the voltage of the eight first electric energy data successively collected all satisfy the following condition: the maximum value among the A-phase voltage, the B-phase voltage and the C-phase voltage is greater than 210V, and the absolute value of the difference between the smaller two-phase voltages is greater than 20V, it is determined that the electric energy meter has voltage abnormality in the fault period, otherwise, the electric energy meter does not have voltage abnormality.

[0042] In S140, the abnormality level is determined according to the voltage and the current in each first electric energy data in the fault period.

[0043] The abnormality level can include a red level and a yellow level, and the red level is higher than the yellow level. Specifically, the way of determining the abnormality level according to the voltage and the current in each first electric energy data in the fault period can be: judging whether the voltage of each phase and the current of each phase satisfy the second abnormality condition corresponding to the connection type; if the second abnormality condition corresponding to the connection type is satisfied, the abnormality level is the red level; if the second abnormality condition corresponding to the connection type is not satisfied, the abnormality level is the yellow level.

[0044] In this embodiment, if the connection type of the electric energy meter is three-phase three-wire, the second abnormality condition is: the A-phase electric energy data in the eight first electric energy data successively collected all satisfy the following condition: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0; or the C-phase electric energy data in the eight first electric energy data successively collected all satisfy the following condition: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0, then it is determined that the C-phase voltage is lost. If the connection type of the electric energy meter is three-phase four-wire (high-supply high-metering or high-supply low-metering), the second abnormality condition is: the A-phase electric energy data in the eight first electric energy data successively collected all satisfy the following condition: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0; or the B-phase electric energy data in the eight first electric energy data successively collected all satisfy the following condition: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0; or the C-phase electric energy data in the eight first electric energy data successively collected all satisfy the following condition: the voltage is less than a certain proportion (such as 78%) of the rated voltage and the current is not equal to 0.

[0045] In the embodiment, when a phase meets the second abnormal condition in the fault period, it is determined that the phase has voltage loss, and a red level alarm information is generated, which includes the phase having voltage loss, the specific time of occurrence and the average voltage of the phase. If any phase does not meet the second abnormal condition, a yellow level alarm information is generated, which includes the unstable voltage of the electric energy meter, the time of occurrence and the average voltage of each phase.

[0046] S150, determine the first, second and third complementary electric energy of the electric energy meter in the fault period.

[0047] The first complementary electric energy is determined based on preset fault data, the second complementary electric energy is determined based on a continuous set number of first electric energy data, and the third complementary electric energy is determined based on the electric energy of the electric energy meter in a historical normal period corresponding to the fault period.

[0048] The preset fault data is obtained by counting the sub-fault data obtained every second preset time.

[0049] Specifically, the preset fault data is obtained in the following manner: the second electric energy data of the electric energy meter is collected every second preset time; when it is determined that the electric energy meter is in a working state according to the current of the three phases, it is determined whether the electric energy meter has voltage abnormality based on the voltage and the rated voltage of the three phases; if the electric energy meter has voltage abnormality, the complementary electric energy in the current second preset time is determined according to the second electric energy data, and the second electric energy data and the complementary electric energy are stored as sub-fault data in the first data table; the sub-fault data in the first data table every first preset time is processed to obtain the preset fault data, and the preset fault data is stored in the second data table; wherein the preset fault data includes average voltage, average current, average power and cumulative complementary electric energy.

[0050] The second electric energy data includes the voltage, current, power and electric energy of the three phases, and the second preset time is less than the first preset time. For example, if the first preset time is set to 15 minutes, the first preset time can be set to 1 minute. Specifically, the manner of determining that the electric energy meter is in a working state according to the current of the three phases can be that the current of each phase is compared with the rated current of a set proportion, and it is determined whether the electric energy meter is in a working state according to the comparison result. The set proportion can be 0.5%. Specifically, if the current of each phase is greater than 0.5% of the rated current, it indicates that the electric energy meter is in a working state, and if the current of one phase is less than or equal to 0.5% of the rated current, it indicates that the electric energy meter is in a non-working state.

[0051] In the embodiment, the manner of determining whether the electric energy meter is faulty based on the three-phase voltage and the rated voltage can be: if the three-phase voltage is greater than or equal to the first proportion (which can be set to 95%) of the rated voltage, the electric energy meter is not voltage abnormal; if at least one of the three-phase voltage is less than the first proportion of the rated voltage, the electric energy meter is voltage abnormal.

[0052] In the embodiment, if the electric energy meter is voltage abnormal, the manner of determining the complementary power in the current second preset time according to the second electric energy data can be: if the phase voltage is less than the first voltage threshold and greater than or equal to the second voltage threshold, the main complementary power is determined based on the phase voltage, the rated voltage, the phase power and the second preset time; if the phase voltage is less than the second voltage threshold, the correction coefficient is determined according to the rated power and the phase power; the complementary power is determined based on the correction coefficient and the phase power.

[0053] In the embodiment, the first voltage threshold and the second voltage threshold are determined by the rated voltage. For example, the first voltage threshold can be the first proportion (95%) of the rated voltage, and the second voltage threshold can be the second proportion (60%) of the rated voltage. When each phase of the three-phase, if the phase voltage is less than the first voltage threshold and greater than or equal to the second voltage threshold, the formula for determining the main complementary power based on the phase voltage, the rated voltage, the phase power and the second preset time can be represented as: W 追补 = P 本相 *(Un-U 本相 ) / U 本相 *t, wherein W 追补 is the complementary power, P 本相 is the phase power, Un is the rated power, U 本相 is the phase voltage, and t is the second preset time. If the phase voltage is less than the second voltage threshold, the calculation formula for determining the correction coefficient according to the rated power and the phase power can be represented as: K = Pu / P 本相 , wherein Pu is the rated power and P 本相 is the phase power. The calculation formula for determining the complementary power based on the correction coefficient and the phase power can be represented as: W 追补 =(K-1)×power.

[0054] In the embodiment, after determining the complementary power of each phase, the voltage, current, power, power and complementary power of each item in the second electric energy data are stored in the first data table as a sub-fault data.

[0055] In the embodiment, after the first data table is obtained, the sub-fault data in the first data table every first preset time is counted to obtain the average voltage, average current, average power and cumulative compensation power of each phase in the first preset time, and the number of sub-fault data contained in the first preset time is counted to obtain preset fault data, and the preset fault data is stored in the second data table.

[0056] Optionally, in order to accurately warn the fault, when the voltage of the electric energy meter is abnormal, the fault can also be classified according to the voltage value. For example, Figure 2 is an example diagram of generating sub-fault data in the embodiment, as Figure 2 shown, the process includes the following steps:

[0057] S201, collecting second electric energy data of the electric energy meter every second preset time.

[0058] S202, judging whether the current of each phase is greater than 0.5% of the rated current, if yes, the electric energy meter is in working state, then executing S203; if no, the electric energy meter is in non-working state.

[0059] S203, judging whether the voltage of each phase is less than 95% of the rated voltage, if no, the electric energy meter does not have voltage abnormality, then executing S204; if yes, the electric energy meter has voltage abnormality, then executing S204.

[0060] S204, judging whether the voltage of each phase is less than 90% of the rated voltage, if no, then executing S205; if yes, then executing S206.

[0061] S205, generating a yellow voltage abnormality warning, and determining the compensation power in the current second preset time according to the first mode, storing the second electric energy data and the compensation power as sub-fault data in the first data table.

[0062] S206, judging whether the voltage of each phase is less than 78% of the rated voltage, if no, then executing S207, if yes, then executing S208.

[0063] S207, generating an orange voltage abnormality warning, and determining the compensation power in the current second preset time according to the first mode, storing the second electric energy data and the compensation power as sub-fault data in the first data table.

[0064] S208, judging whether the voltage of each phase is less than 60% of the rated voltage, if no, then executing S209; if yes, then executing S210.

[0065] S209, generate a red voltage abnormality early warning, determine a current second preset time's complementary power in a first mode, store the second electric energy data and the complementary power as sub-failure data into a first data table.

[0066] S210, generate a red voltage abnormality early warning, determine a current second preset time's complementary power in a second mode, store the second electric energy data and the complementary power as sub-failure data into a first data table.

[0067] The first mode is to determine a main complementary power based on the phase voltage, the rated voltage, the phase power and the second preset time. The second mode is to determine a correction coefficient according to the rated power and the phase power, and determine a complementary power based on the correction coefficient and the phase power.

[0068] Specifically, after obtaining the preset failure data, the cumulative complementary power in the preset failure data in the second data table falling within the failure period is accumulated to obtain a first complementary power. The second complementary power is calculated by accumulating the complementary power corresponding to a continuous set number of first electric energy data within the failure period. The calculation formula of the complementary power corresponding to the first electric energy data can be represented as: W 追补 = P 本相 *(Un-U 本相 ) / U 本相 *T, wherein W 追补 is the complementary power, P 本相 is the phase power, Un is the rated power, U 本相 is the phase voltage, and T is the first preset time. The third complementary power can be determined by subtracting the power of the electric energy meter in the historical normal period corresponding to the failure period from the power in the failure period.

[0069] S150, determine the target complementary power of the electric energy meter according to the abnormality level, the first complementary power, the second complementary power and the third complementary power.

[0070] In this embodiment, the abnormality level is different, and the way of determining the target complementary power is also different.

[0071] Optionally, the way of determining the target compensation electric quantity of the electric energy meter according to the abnormality level, the first compensation electric quantity, the second compensation electric quantity and the third compensation electric quantity can be: if the abnormality level is the yellow level, determining the ratio of the difference between the first compensation electric quantity and the second compensation electric quantity to the second compensation electric quantity; if the absolute value of the ratio is less than the set proportion, determining the first compensation electric quantity as the target compensation electric quantity; if the absolute value of the ratio is greater than or equal to the set proportion, determining the ratio of the difference between the first compensation electric quantity and the third compensation electric quantity to the third compensation electric quantity; if the ratio is less than the set proportion, determining the first compensation electric quantity as the target compensation electric quantity; if the ratio is greater than or equal to the set proportion, determining the third compensation electric quantity as the target compensation electric quantity.

[0072] The set proportion can be set as 10%, and the ratio of the difference between the first compensation electric quantity and the second compensation electric quantity to the second compensation electric quantity can be represented as (W1-W2) / W2. The ratio of the difference between the first compensation electric quantity and the third compensation electric quantity to the third compensation electric quantity can be represented as (W1-W3) / W3.

[0073] Optionally, the way of determining the target compensation electric quantity of the electric energy meter according to the abnormality level, the first compensation electric quantity, the second compensation electric quantity and the third compensation electric quantity can be: if the abnormality level is the yellow level, determining the ratio of the difference between the first compensation electric quantity and the second compensation electric quantity to the second compensation electric quantity; if the absolute value of the ratio is less than the set proportion, determining the first compensation electric quantity as the target compensation electric quantity; if the absolute value of the ratio is greater than or equal to the set proportion, determining the ratio of the difference between the first compensation electric quantity and the third compensation electric quantity to the third compensation electric quantity; if the ratio is less than the set proportion, determining the first compensation electric quantity as the target compensation electric quantity; if the ratio is greater than or equal to the set proportion, determining the third compensation electric quantity as the target compensation electric quantity.

[0074] The set proportion can be set as 10%.

[0075] Exemplarily, Figure 3 is a flow chart for determining the target compensation electric quantity in the embodiment, as shown in Figure 3 the process includes the following steps:

[0076] S301, determining the abnormality level according to the voltage and the current in each first electric energy data in the fault period; if the abnormality level is the yellow level, executing S302; if the abnormality level is the red level, executing S304.

[0077] S302, determining the ratio of the difference between the first compensation electric quantity and the second compensation electric quantity to the second compensation electric quantity.

[0078] S303, judging whether the absolute value of the ratio is less than 10%; if not, executing S304; if yes, executing S306.

[0079] S304, determining the ratio of the difference between the first compensation electric quantity and the third compensation electric quantity to the third compensation electric quantity.

[0080] S305, determining whether the absolute value of the ratio is less than 10%, if yes, executing S306, if no, executing S307.

[0081] S306, determining the first complementary electric quantity as the target complementary electric quantity.

[0082] S307, determining the third complementary electric quantity as the target complementary electric quantity.

[0083] The technical scheme of the embodiment collects first electric energy data of the electric energy meter every first preset time; wherein, the first electric energy data includes three-phase voltage, current, power and electric quantity; when it is determined that the electric energy meter is in a working state according to the three-phase current, the wiring type of the electric energy meter is obtained; wherein, the wiring type includes the following three types: three-phase three-wire, three-phase four-wire high-supply high-metering and three-phase four-wire high-supply low-metering; if the voltage in the continuous set number of first electric energy data meets the abnormal condition corresponding to the wiring type, it is determined that the voltage of the electric energy meter is abnormal in the fault period; wherein, the fault period is the period in which the continuous set number of first electric energy data is collected; the voltage and current in each first electric energy data in the fault period are determined to determine the abnormal level; the first complementary electric quantity, the second complementary electric quantity and the third complementary electric quantity of the electric energy meter in the fault period are determined; wherein, the first complementary electric quantity is determined based on the preset fault data, the second complementary electric quantity is determined based on the continuous set number of first electric energy data; the third complementary electric quantity is determined based on the electric quantity of the electric energy meter in the historical normal period corresponding to the fault period; the target complementary electric quantity of the electric energy meter is determined according to the wiring type, the first complementary electric quantity, the second complementary electric quantity and the third complementary electric quantity.
